Recultivation

• Re-use, re-utilisation

• Technical, biological, agronomic processes

• Fertilize land, which was made barren

• Purpose of forestry, agriculture, horticulture or other economic activities

Technical phase

• Adaptation of spoil banks

• Restoration of the water routine

• Adaptation of the water regime

Technical phase

• Adaptation of spoil banks

• Restoration of the water routine

• Layer of fertile soil

• Adapted spoil banks are covered with a fertile soil

Biological phase

• Green fertilization– Introductory doses of nitrogen– Large amount of organic matter

• Final cultures– Farmland, vineyards, orchards– Forests

Demonstrations of succesfull recultivation

Vineyards are founded on south-exposed slopes

Orchads
